Abstract
A head-mounted display system includes a waveguide configured to guide light from a light projection system coupled into the waveguide; a grating structure optically coupled to the waveguide, the grating structure being configured to couple light from the light projection system into the waveguide. The grating structure includes a grating layer having a grating with multiple ridges having ablaze profile in at least one cross-section, the blaze profile having an anti-blaze angle of 85° or less; and one or more additional layers on the grating layer, the additional layers including a first layer of a material having a refractive index of 1.5 or less at an operative wavelength of the head-mounted display, the first layer being an outermost layer of the grating structure.
